I'm using an Athlon XP 2200+ on an Epox 8K3A+ with an Alpha PAL8045 heatsink and a Panaflo M1A (32.1CFM) fan on top of the heatsink, and no matter how many times I reseat my heatsink, I pretty much get around 57C cpu temp. My case temp is 24C, so I don't think airflow is much of a problem. I've heard that some motherboards read the internal cpu temp and others the outside temp. I haven't been able to find any information on how the Epox 8K3A+ reads the CPU temp. If anyone could give me some insight into this, it'd be much appreciated. Otherwise, I'm gonna buy a jet engine fan to cool that puppy down.
